Abstract (en)
[origin: US2018315909A1] The present application discloses a pixel structure and method for the fabrication thereof including: providing a substrate; forming a black photoresist layer having a receiving cavity and an isolation region on the substrate; coating a polyelectrolyte solution on the surface of the black photoresist layer except the isolation region, and air-dried to form a polyelectrolyte layer; coating a metal nanoparticle solution on the surface of the polyelectrolyte layer, and air-dried to form a metal particle layer; and align and transferring a micro light emitting diodes to the black photoresist layer. In the above-described manner, the present disclosure can improve the light utilization efficiency of the micro light emitting diode.
